Description

BaerCoil BSF 3/8 x 20 thread inserts are precision stainless-steel solutions designed to repair and reinforce BSF threads with maximum reliability. Crafted from AISI 304 stainless steel and engineered for high-strength performance, these inserts offer durable, long-lasting joints in a compact, space-efficient form.

  • Material: AISI 304 stainless steel (austenitic chromium-nickel steel) with a tensile strength of at least 1400 N/mm2 for superior robustness and corrosion resistance.
  • Cross‑Section: Rhombic profile achieved through cold-form swaging, providing even load distribution and efficient thread engagement.
  • Thread Size: BSF thread in 3/8" diameter with 20 threads per inch, matching standard British Fine specifications.
  • Insertion Depth: Designed for 2xD engagement to maximize holding power and reduce the risk of thread pull-out.
  • Manufacturing Process: Cold-formed swaging creates a precise rhombic shape that enhances thread contact and space utilization inside the fastened joint.
  • Performance Benefits: Improves wear resistance, thread abrasion resistance, surface finish, corrosion resistance, and heat resistance compared with conventional single-screw connections.

BaerCoil inserts are engineered to deliver durable, secure threads in demanding applications. By restoring damaged BSF threads and reinforcing the joint, they help extend service life, reduce maintenance, and maintain consistent torque transfer across cycles. The combination of stainless steel chemistry and the rhombic swaged geometry means reliable performance in environments where corrosion, heat, and wear are concerns, making them a smart choice for precision assemblies and repair tasks.
